Verifying Your VMware License Version

Use this procedure, before beginning to troubleshoot any installation issues, to verify that your ESX server has the VMware Enterprise Plus license which includes the Distributed Virtual Switch feature.

Refreshing the vCenter Server Connection

Use this procedure to refresh the connection between the Cisco Nexus 1000V and vCenter Server.

Step 1 From the Cisco Nexus 1000V Connection Configuration mode on the VSM, enter the following command sequence:

Example:

n1000v# config t

n1000v(config)# svs connection s1

n1000v(config-svs-conn)# no connect

n1000v(config-svs-conn)# connect

Step 2 You have completed this procedure.

Improving Performance

Use the following pointers to improve performance on the ESX host and the VMs.

•Install VMware Tools on the vCenter Server VM, with Hardware Acceleration enabled to the full.

•Use the command line interface in the VMs instead of the graphical interface where possible.

Verifying the Domain Configuration

The Virtual Supervisor Module (VSM) and Virtual Ethernet Module (VEM) are separated within a Layer 2 domain. To allow VSM-VEM pairs to communicate within the same Layer 2 domain, each pair must have a unique identifier. The domain ID serves as the unique identifier that allows multiple VSM-VEM pairs to communicate inside the same Layer 2 domain.

Following the installation of the Cisco Nexus 1000V, make certain that you configure a domain ID. Without a domain ID, the VSM will not be able to connect to the vCenter Server. Follow these guidelines:

•The domain ID should be a value within the range of 1 to 4095.

•All the control traffic between the VSM and the VEM is carried over the configured control VLAN.

•All the data traffic between the VSM and the VEM is carried over the configured packet VLAN.

•Make sure the control VLAN and the packet VLAN are allowed on the port in the upstream switch to which the physical NIC of the host hosting the VSM and VEM VM are connected.

Verifying the Port Group Assignments for a VSM VM Virtual Interface

Use this procedure to verify that two port groups are created on the ESX hosting the VSM VM through the vCenter Server. The following port groups (PG) should be created:

•Control PG (Vlan = Control VLAN)

•Packet PG (Vlan = Packet VLAN)

•Management PG (Vlan = Management VLAN)

Make sure the port groups are assigned to the three virtual interfaces of the VSM VM in the following order:

Virtual Interface Number

Port Group

Network Adapter 1

Control PG

Network Adapter 2

MGMT PG

Network Adapter 3

Packet PG

To verify if the VSM VM network adapter 1, network adapter 2, and network adapter 3 are carrying the control VLAN, management VLAN, and the packet VLAN, follow these steps:
